Answer: Sampling theory states that a band limited continuous time signal with highest frequency equal to BHz can be recovered from its sample provided the sampling frequency Fs is greater than or equal to 2B Hz. The minimum sampling rate is called Nyquist rate
Fsminimum = 2B
Famine = 2 * 155 = 310 * 1000 = 310,000 Hz or samples per second
Therefore the minimum sampling rate = 310,000Hz or samples per second
